1. Please describe the problem: The whole system crashed with a black screen, error trace QR-Code, and the title "Kernel panic! Fatal exception in interupt" on 7.1.8-200.fc44.x86_64 during a Google Meet call with a screen being shared, while Podman containers, VSCode, and Slack were running in the background. 2. What is the Version-Release number of the kernel: 7.1.8-200.fc44.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : First time this happened to me. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: I did not managed to reproduce it. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: I did not managed to reproduce it. 6. Are you running any modules that not shipped with directly Fedora's kernel?: I don't think so. 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag.

not syncing: Fatal exception in interrupt [522705.613758] Kernel Offset: 0xd200000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff) Reproducible: Always
Same instruction as bug 2521546, decoded from your inline Oops: the Code bytes at skb_clone+0x159 are "f0 ff 42 20" = lock incl 0x20(%rdx), the atomic_inc on skb_shinfo(skb)->dataref, with RDX = ffff8a73736d279f. That puts dataref at ...27bf, byte 63 of a 64-byte cache line, so the 4-byte atomic straddles two lines: a kernel-mode split lock, fatal on Intel. skb->head is misaligned by 0x1f because it came from a page_pool fragment at an odd offset -- your module list has veth/bridge (Podman), and veth's skb_pp_cow_data() is one of the callers that leaves the pool's fragment offset odd. Upstream fix, in net.git with Cc: stable: https://git.kernel.org/netdev/net/c/dc0df5a0c62c Fedora 44 backport MR: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/4730 Workaround until it lands: boot with split_lock_detect=off.
